Quizzes
MCQ, true/false and fill-in-the-blank — each answer comes with the reason it is right. A wrong answer teaches you something instead of just costing a point.

Generates in seconds
One document. Four ways to study it.
Most study apps ask you to type your own cards. That work is the reason people give up.
Flashcards
Spaced repetition, the method Anki popularised. Every card returns at the moment you are about to forget it, not on a fixed timetable.
Summaries
Structured from your document’s own headings, and listenable as a podcast — so a commute becomes a revision session.
Open questions
Exam-style long answers, graded by AI with feedback and a model answer. The format most apps skip because it is hard.
Ask Twixem
A tutor that read your course.
Stuck on a question? Type “I don’t understand” and it explains like a teacher — grounded in your own document, not in generic answers scraped from the internet.
Which means it cannot invent a definition your professor never gave, and it can point you to the page it came from.
I don’t understand question 3
Your notes define it on page 12: it’s the stage where light energy is captured, before any sugar is built. That’s why the answer isn’t respiration — respiration releases energy, it doesn’t capture it.

The coach
It finds the gaps you’d avoid.
After each quiz, Twixem identifies the concepts you keep missing and builds a targeted mini-quiz from them. Calculated from your real results, not from what you say you struggle with.
Because the topics you avoid are precisely the ones costing you marks.
Make it stick until exam day
A plan that survives a bad week.
Set your exam date
The plan recalculates daily around what you keep getting wrong. Miss a day and it redistributes — a plan that punishes one bad week is a plan people abandon.
Reminders that count down
“D‑12 — 8 cards are waiting.” Not a generic nudge: your cards return when your memory needs them.
Your document is a workspace
Imported once, kept forever. Quizzes, mistakes, decks, summaries, tutor conversation and concept map — all in one place.
